title: Enhancing effect of corticotropin-releasing neurohormone on the production of interleukin-1 and interleukin-2.
abstract: Based upon an immunomodulatory role for Corticotropin-Releasing Factor (CRF), a low molecular weight neurohormone, we investigated the effect of CRF on the production of interleukin-1 (IL-1) and interleukin-2 (IL-2) activities of mononuclear cells isolated from the peripheral blood of healthy subjects. The production of both IL-1 and IL-2 was stimulated by a nanomolar concentration of CRF by itself. In addition, CRF augmented the production of IL-1 as induced by lipopolysaccharide and the production of IL-2 as induced by phytohemagglutinin. These results suggest that CRF modulates the function of the cells of the immune system presumably by acting as a blood-borne mediator of the neuroendocrine-immune pathways.
